How to measure strain using fiber Bragg gratings
This paper gives a short introduction to FBG sensors, points out their special strengths and weaknesses and describes a measuring system which enables strain gages and FBGS to be measured simultaneously, providing all data processing functions originally developed. The work is devoted to the consideration of methods for determining the strain of objects using fiber Bragg gratings under a high-frequency vibration or pulsed mechanical action, which is difficult to perform using widespread methods and devices. A fiber Bragg grating is a small length of optical fiber that comprises a pattern of many reflection points that creates a reflection of particular wavelengths of incident light.

Simulation of Fiber Bragg Grating Strain Sensor
In this study, the Fibre Bragg grating (FBG) is modelled, simulated, and characterised with respect to maximum reflectivity, bandwidth, the impact of applied strain on the wavelength shift, ?B, and the wavelength shift sensitivity with strain for an optical. The work is devoted to the consideration of methods for determining the strain of objects using fiber Bragg gratings under a high-frequency vibration or pulsed mechanical action, which is difficult to perform using widespread methods and devices. Keywords Strain sensor; Bragg wavelength shift, Temperature sensor, Poisson ratio I. INTRODUCTION Optical fiber sensors are gaining popularity due to their numerous benefits, including: immunity to electromagnetic interference, intrinsic fire safety, low invasiveness, and the ability to send data.
